A:AnswerPhysically this will fit in it and it is going to be a nice upgrade from the previous card.
Couple of things to consider.
This card needs a PCIex16 slot.
It needs a power supply of 300w or more.
A:AnswerYes. As long as you have a PCIx slot, the space in the tower, and a reasonable power supply (> 380W), you'll be fine. Any CPU will work with it.
A:Answerunfortunately i don't know on the first question but the second question i can answer. i have been able to play my game (Subnatica) and it works really well.
A:AnswerI put it in new machines with power supplies with smaller wattage ratings than recommended, and it worked. However, I did not stress the card beyond video streaming and DVD playback. A power supply change is easy to do.
A:AnswerFortnite uses more of CPU cores to run but video card might help with some visuals.This one would be able to support the game on a very low settings with fast Internet connection, but would advise against it.Maybe go one level higher and spend $120-$140 fo better one.
A:AnswerIt is dual-width, meaning that you can't use the slot next to it because of the cooling fins.
It requires at least a 300 watt power supply. I installed it in a PC with a 300 watt power supply and it works very well.
I recommend it for a low cost video card to run Steam games.
